| Abstract: | In order to ensure the safe operation of a metro vehicle,the strength of its axle was analyzed.According to the calculation method of material mechanics in standard EN13103,seven sections of the axle were determined,and the resultant moment,stress and safety factor of the sections were calculated.The results showed that the dangerous sections of the axle were located at the arc transition between the wheel seat and the brake disc seat,and the arc transition between the brake disc seat and the axle body,and the stress of maximum calculated was less than the allowable stress,which met the design requirements of the axle strength. |
